Mission X: Train Like an Astronaut (2026–2027)

Mission X: Train Like an Astronaut is a free, international educational school project run by ESA and partners that challenges students to train like astronauts through physical exercises and scientific investigations. It combines fitness missions with STEM-related scientific activities focused on health, nutrition, human biology and the effects of microgravity. The project provides ready-to-use resources for teachers, online submission of results, and a certificate of participation for students. Each school year features the Walk to the Moon Challenge in which teams earn virtual 'steps' by completing activities.

Access to ready-to-use educational resources, physical activity videos, official Mission X certificate of participation, and a special celebratory message from an ESA human spaceflight expert for Walk to the Moon Challenge participants.

Participation is open worldwide to individuals or teams of students aged up to 19 years old (recommended 5 to 14); activities may be submitted by registered teachers or educators.

Teachers or educators register on the Mission X website and submit team activity results online for the Walk to the Moon Challenge.
